If I'm showing signs and symptoms of hiv, even if its before the window period is up, will I be able to test positive?
It is very unlikely that your symptoms are due to HIV, if you are in the window period. By definition, antibody tests are negative in the window period. If you get an HIV nucleic acid test, that is the earliest test to turn positive in a person with HIV. But a negative result on a test done too soon does not rule out infection.

Window periods hiv test. I had 4 test hiv combo after 94 days negative. But my country state window period 6 month. Malaysia.?
4 weeks. Believe it.: Only a few companies make most of the HIV tests used worldwide. The window period for the combo test (also called duo or 4th generation test) is the same everywhere, 4 weeks. That a particular health department or agency takes a conservative stance and promotes longer periods is a decision based on legalities, politics, and social context. I can't say why some agency in Malaysia says 6 months. ...Read more
